Calexico makes its third appearance on Mountain Stage, recorded in front of a sold-out audience in Charleston, W.Va. Founded by singer-guitarist Joey Burns and percussionist John Convertino, Calexico has spent nearly two decades fusing spaghetti Western themes, surf music and alt-country into evocative desert rock. The band's lineup has expanded to include Jacob Valenzuela and Martin Wenk on trumpet, Sergio Mendoza on keyboards, Ryan Alfred on bass and Paul Neihaus on pedal steel.

Based in Tucson, Ariz., the group counts fellow Arizonan and astronaut Mark Kelly among its greatest fans. Kelly used Calexico's "Slowness" as a wake-up song on the final flight of Space Shuttle Endeavor. The band's latest album, Algiers, was recorded in the New Orleans neighborhood of the same name.
